“in which only intensive quantities remain tensorial.”

“Second, T ν μ contains the contribution of the energy-momentum density of only nongravitational matter plus fields, thus lacking the contribution of the gravitational energy-momentum density”

“First, it is a tensorial condition, T ν μ ; ν = 0, that replaces in GR the null divergence T ν μ , ν = 0.”

“both the intensive (L) and extensive (EXT) quantities of Equation3.1, particularly Q α 1 ⋯ α j ⋯ α n , are all tensorial quantities in the sense that they transform as tensors with respect to Poincaré transformations in Minkowski spacetime within the set of inertial coordinates.”

“The physical motivation for part (b) of (Equation4.1) was anticipated in Section3.1: an electromagnetic system in the classical limit of a particle- and charge-conserving continuum fluid and a two-component system composed of the charged fluid itself with specified initial conditions (one sub-system) plus its own electromagnetic field (the second sub-system), both dynamically acting on one another”

“Bianchi's identity, G ν μ ; ν ≡ 0, is a geometric one, which means that it is valid for an arbitrary metric tensor g μν regardless of whether it is or not a solutio n of (Equation2.1)”
